Product Introduction and Advantages
1. Definition and Usage
Conical rollers are key components of belt conveyors, mainly used in conveyor turning sections or deviation adjustment areas. Their unique conical structure can automatically correct belt deviation, ensuring stable conveyor operation. They are suitable for bulk material conveying systems in industries such as mining, ports, power plants, and building materials.
2. Structural Features
Conical Design: The rollers are conical (single or double cone), and the diameter difference generates axial force to guide the belt back into position.
Material Selection:
Roller Body: High-quality seamless steel pipes or polymer materials (wear-resistant, corrosion-resistant).
Bearings: High-precision deep groove ball bearings or sealed bearings (dustproof, long lifespan).
Shaft: Carbon steel or alloy steel, after quenching treatment, high strength.
Sealing System: Multi-layer labyrinth seal + lithium-based grease, dustproof, waterproof, suitable for harsh environments.
3. Type Classification
Forward-inclined conical rollers: Active correction, installed at a certain forward angle.
Self-aligning conical rollers: Equipped with a rotating bracket for dynamic adjustment of the belt direction.
Buffer conical rollers: With rubber rings to reduce impact from falling materials and protect the belt.
Core Advantages
1. Efficient Deviation Correction, Reduced Maintenance Costs
Automatically adjusts belt deviation, reducing manual intervention, and downtime is reduced by more than 30%.
Avoids belt edge wear, extending the service life of the conveyor belt by 2-3 times.
2. Stable Operation, Reduced Loss
The conical structure disperses belt pressure, reduces vibration, and reduces running resistance by 15%-20%.
Precise dynamic balance design, speed up to 4.5m/s, noise below 75dB.
3. Strong Adaptability
Operating temperature range: -30℃ to +120℃, acid and alkali resistant, anti-corrosion (optional stainless steel or ceramic coating).
Supports customization: Taper (usually 1°-5°), length, bearing type customized according to working conditions.
4. Energy Saving and Environmental Protection
Low friction coefficient design, saves 8%-12% electricity compared to traditional rollers.
Maintenance-free or low-maintenance design, reducing lubricating grease pollution.
5. Long Lifespan Design
Bearing life exceeds 50,000 hours, roller body wear-resistant layer thickness ≥6mm, comprehensive service life up to 3-5 years.
Application Scenarios
High-precision conveying: such as food and packaging industries, requiring no belt deviation.
Harsh environments: Underground coal mines (explosion-proof type), chemical zones (corrosion-resistant).
Long-distance conveying: Port yards, mine inclined shafts, reducing the number of deviation correction devices.
